What I've previously chosen was a Corsair RM650X 2018, but the same version of 750W is just 5€ more expensive, and I thought that it could leave some more room to play, but I am not entirely sure if I will ever use more than the half of it.

So my question in the end is, based on the component list, what is the recommended wattage for a mid-overclocker(beginner) and if there's any other PSU recommendations.

The point of this build is for gaming and programming.
Average usage time: 5h~ per day(excluding weekends).
Location: Germany

This will be a open case, so having some good looking cables would be an extra point to consider, after quality and reliability of course.

Every help and opinion is highly appreciated!

If you find anything else that can still be upgraded/changed on the component list, feel free to add it on your comment and an explanation why!

Any particular reason why choosing the Seasonic? I've read that they're good, but I've also read that there are some issues.. that made me change from my initial PSU to the current one. If you've any points, where you could explain me why the Seasonic would be a better choice, or any other PSU, I would highly appreciate it!

In regards to the Ryzen, I will take a look at the mobo QVL to assure that it is compatible, at those running speeds

Also still in regards to changes in the build, I am willing to spend more, if I do understand what the build is gaining with it!
